The observations by coastal hydrometeoro-logical stations pertaining to the given area can be 

 significant only when small water basins are investigated. A few examples from any experiences 

 can clearly illustrate the statement. 



It was said that a belt of relatively scattered ice constitutes an area with frequently occurring 

 fog. Figure 4 presents schematically the situation of fog over the Barents Sea at weak wind blow- 

 ing from scattered ice edges. It is seen from the scheme that the fog, lying tight on the ice, is 

 gradually rising as it moves away from the ice edges, and that, at a sufficient distance from the 

 ice, the fog turns into cloudiness. Figure 5 also schematically presents a vertical cross section of 

 atmosphere based on my observations during the flight with Vodopyanoo over the Kara Sea on 31 

 May 1939. During the flight it seemed that the aircraft entered the open mouth of a gigantic mon- 

 ster. The phenomenon was attended by a weak wind from the open sea toward the ice edge.
